[PATCH] ACPICA: Replace one-element array and use struct_size() helper

2020-05-18 Thread Gustavo A. R. Silva
The current codebase makes use of one-element arrays in the following form: struct something { int length; u8 data[1]; }; struct something *instance; instance = kmalloc(sizeof(*instance) + size, GFP_KERNEL); instance->length = size; memcpy(instance->data, source, size); but the preferre
